PROCESS FOR MAKING CLEANING COMPOUNDS.

No Drawing.

To all whom it may concern:

Be it known that I, ARTHUR IV. BISHOP, a citizen of the United States, residing at St. Louis, in the State of Missouri, have invented certain new and useful Improvements in Processes for Making Cleaning Compounds, of which the following is a specification.

This invention has relation to cleaning compounds, and the primary object thereof is to provide a compound containing a new and novel combination of detergents and other substances for promoting the action of the detergent.

Another object of the invention is to provide a compound of the character set forth for use in conjunction with soaps in removing obstinate stains from the hands or clothing.

In addition to the foregoing my invention comprehends the novel combination of ingredients and the proportions by which they are combined, to be hereinafter described and particularly set forth in the appended claims.

To proceed with a detailed description of the technical operation for bringing together the ingredients of this compound. 120 parts of soft water are placed in a suitable receptacle which is adapted to be moved occasionally to agitate its contents. Into the water in the receptacle, there is placed 20 parts of sodium sulfid, and three parts of sodium hydro-oxid (caustic), and 24 parts of mangaf, eff ioxid. The receptacle is agitated bccasionally for two or three days until the chemicals are dissolved. The temperature of the water should be in the neighborhood of F., but under no circumstances should heat be employed.

After the expiration of the above mentioned period, 31} parts of sodium chlorate, and 3 parts of sifted soft coal ashes "lire placed in the receptacle, the contents thoroughly agitated and permitted to stand for approximately four days. After the expiration of the period of settlement, the clear portion of the liquid is decanted into another receptacle, and into said decanted portion four parts of il of mirbane are added. Owing to the heavy specific gravity of the undissolved material, filtering is unnecessary. This clear solution may then be dispensed in bottles, with directions to shake the bottle before the compound is used.

fluid for a moment and then soap is used to I work up a lather. \Vhen the cuticle has become softened the same may be easily removed. Rinsing in clear water will then remove all of the compound and the hands will be found to be clean and removed of all the stains.

This compound is especially efficacious in removing acid stains from the fingers as well as removing chemical dyes, indelible ink stains, etc. In view of my experience, if

e compound is usedin the manner stated it will not injure the skin.

The effectiveness of the compound resides to a great extent in the oxygen contained therein and the unstable combination of the oxygen whereby it may be readily liberated thereby acting somewhat as a. bleaching agent. The oxygen is probably in the form of sodium peroxid brought about by the combination of the hydrate with the manganese dioxid. A small quantity of sodium man anate is also formed which is an adfiiiia bl? disinfectant, or antiseptic. Chlorin is also liberated to some extent by reason of the action of a small quantity of sulfuric acid in the soft coal ashes, acting upon the sodium chlorate.

lVhile I have described my invention with some degree of particularity, and brought the proportions of the ingredients into an exact formula, I wish it understood that I do not restrict myself to the exact proportion of the ingredients stated therein, but reserve the privilege of changing the proportion, or the manner in which they are combined, Without departing from the spirit of the invention or the scope of the appended claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

1. The herein described method of making a cleaning compound, which consists in forming an aqueous solution of the sulfid and hydro-oxid of sodium, in suitable proportions, adding manganese dioxid to eliminate the sulfurous odor, adding sodium chlorate and sifted soft coal ashes containing an acid in suitable proportions, whereby free chlorin is liberated, decanting the clear portion of the liquid after the expiration of a predetermined period, and adding oil of mirbane to the solution.

2. The herein described method of making a cleaning compound which consists in forman aqueous solution of twenty parts of so ium sulfid and three parts of sodium hydro-oxid in one hundred and twenty parts of water, adding twenty-four parts of man-- ganese dioxid, and agitating the combination until the sulfurous odor has been eliminated, adding three and one-half parts of sodium chlorate and three parts of sifted ARTHUR W. BISHOP.
